Migrated information
Conclusions:
The dermal LD50 for rats is > 4 ml/kg (~3400 mg/ kg bw).
Executive summary:

This study examined the acute toxicity of Dilutine M5 to rats via dermal exposure. 2 female and 2 male rats were exposed to 1, 2, or 4 ml/kg of undiluted test material dermally for 24 hrs. No rats died during the experiment. The dermal LD50 for rats is > 4 ml/kg (~3400mg/kg bw).
